p-Methoxyphenol: A potent and effective scavenger for solid-phase peptide synthesis.

During the final step of t-Boc/Bzl, solid-phase peptide synthesis (SPPS)-protecting groups from amino acids (aa) side chains must be removed from the target peptides during cleavage from the solid support. These reaction steps involve hydrolysis with hydrogen fluoride (HF) in the presence of a nucleophile (scavenger), whose function is to trap the carbocations produced during S 1-type reactions. Five peptide sequences were synthesised for evaluating p-methoxyphenol effectiveness as a potent scavenger.

Specific Binding Peptides from Rv3632: A Strategy for Blocking Entry to Target Cells?

Tuberculosis is an infectious disease caused by (, i.e., the aetiological agent); the WHO has established this disease as high priority due to its ensuing mortality.

Critical role of HLA-DRβ* binding peptides' peripheral flanking residues in fully-protective malaria vaccine development.

A vaccine candidate component must fit perfectly into the antigen presenting HLA-DRβ* molecule's groove (or canonical nonapeptide) peptide binding region (PBR) during antigen presentation to the T-cell receptor (TCR), conforming a specific and stable macromolecular complex and induce an appropriate immune response. Antigen's peripheral flanking residues (PFR, positions (p) -p2 and p10) must thus establish strong interactions with the HLA-DRβ* - TCR complex. These amino acids (aa) have specific physico-chemical characteristics enabling differentiation between non-protective but antibody-inducer (NPAI), short-lived protection inducer (SLPI) and long-lasting protection inducer (LLPI) peptides when used as an antimalarial vaccine component.
